Specification of Letters Patent.

Patented May 23, 191% To all whom it may concern:

Be it known that 1, WILLIAM P. DILTS, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Siphonl-Ieads, of which the following is a specification.

This invention relates to improvements in siphon heads and its object is to simplify the construction, reduce the cost and to promote the efilciency of these devices, to provide a siphon head which shall be more sanitary than any construction now used or known, and which shall be incapable of breakage or destruction; and finally, to provide a siphon head having a connection of the most efiicient character with the bottle with which it is combined and with the siphon tube which projects into said bottle.

The above objects are attained by a construction wherein the siphon head is composed of compressed non-corrosive material, such, for example, as is used for electrical insulation and is well known under the trade names of bakelite or condensite or hiheat, the said head being pressed into the shape determined upon and the dies used in this operation forming the interval chamber and liquid ducts.

The invention also involves a novel relation between the siphon head and the bottle, between the siphon head and the siphon tube which projects into the bottle, and between the siphon head and the valve; and finally,

a novel construction of valve.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical, longitudinal sectional view of a siphon head in which the features of the invention are incorporated, the valve being shown in closed relation; Fig. 2 is a fragmentary view similar to Fig. 1, the valve, however, being shown in open relation; Fig. 3 is a detail sectional view of certain features of the valve; Fig. 1 illus trates in elevation, top and bottom plan, a core which enters into the construction of the valve; Fig. 5 is a detail'elevation, partly in section, of the valve; Fig. 6 is a detail sectional view showing the relation between the valve and its operating button or plunger; Fig. 7 is a detail sectional view showing the relation between the siphon tube and the sleeve which connects said tube and the siphon head; Fig. 8 is a bottom plan view thereof.

Similar characters of reference designate corresponding parts throughout the several views.

The siphon head, designated generally as 1, is composed wholly of a material which is exceedingly tenacious, substantially nonbreakable, non-corrosive, impervious to moisture or gas, and capable of being pressed or molded into the shape desired and of permanently retaining said shape without further treatment. Material of the same character is used in the make-up of various parts of the construction which will be specifically pointed out as the description proceeds. A material which satisfies the requirements stated and which, so far as I am now aware, is the most suitable for the purposes in view, is the compressed noncorrosive material which is in common use at the present time as an electrical insulation and is well known under the trade names of bakelite, condensite or hiheet, this material being a molding mixture composed of a condensation product of phenol and formaldehyde or its equivalents and a suitable filling, such as asbestos or vegetable fiber.

The siphon head disclosed relates broadly to the type of construction shown, for example, in the Lukacsevics Patents No. 1,040,226, granted October 1, 1912, and No. 1,061,857, granted May 13, 1913, which type of construction embodies the siphon head proper 1 having the liquid discharge duct 2 and an axial bore communicating with said duct the said bore having at its lower end a relatively large valve chamber 3 and in wardly of said valve chamber a liquid passage 4:; a valve designated generally as 5 and co-acting with a seat 6 intervening be tween the chamber 3 and the passage 1; a valve-operating button 7 arranged in an axial recess 8 at the upper end of the siphon head, a spring 9 acting on the button and tending to hold the valve normally closed;

and a neck ring which surrounds the neck of the bottle and secures the siphon head in position. The siphon head is of course employed in connection with the usual siphon tube 11 which projects into the bottle.

The combination of'elements above specified is common to the'type of construction disclosed in the said Lukacsevics patents,

but the present invention involves substantial dllferences 1n the construction of certain specified elements of said combination,

. and certain differences in' the relation of particular elementsof the combination.

The siphon head proper 1 is composed of compressed noncorrosive material, as above explained, and this same materlal is used in the productlo-n of the neck ring 10;

terial, and construction.

The valve chamber 3 is internally threaded'as at 17 and the sleeve 12 is externally threaded, its threads matching with the threads 17. The said sleeve is fitted in the lowerportion 0f the valve chamber and is thus joined directly to the siphon head. The upper end of the tube 5 fits snugly within J the sleeve and said tube is preferably posi- 'tively held against movement relative to said sleeve'by the agency of cement 18' arranged adjacent the upper and lower ends of the sleeve. The sleeve 12 thus provides a rigid reason of the factthat the gasket 16, apart connection between the siphon tube 11 and the siphon head. Liability of breakage of the bottle byreason of a sudden jar imparted to thesiphon head is prevented by vfro'ni'its sealing function, provides a cushion which takes up ars. To provide for its convenient application to and removal from the siphon head, the sleeve 12 is made of a r square cross section as shown in Fig. 8.

The valve 5 includes a core 19 in the form of acorrugated metal bar of square cross section, said core having 'a bifurcated lower end 19 of inverted V-shape. The

valve alsojincludes a sleeve '20 which surrounds the core 19 and is composed of the same .material' as the" head 1, 6. 9., compressednon-corrosive material, as above de scribed, the said sleeve being compressed or molded about the said'core. The sleeve 20 atits lower end is formed with a double coniform head 2 1 whichis compressed or 'molded upon the bifurcated end 19 of the core. The head 21 constitutes the body of the valve proper and is complemented by a relatively soft rubber facing 22 which is vulcanized upon said head, the material of which said head is composed, e. 9., compressed non-corrosive material, being cape ble of withstanding vulcanizing heat. The marginal portions of the rubber facing 22 bear against shoulders 23 and 24:, the shoulder 23 surrounding the head 21 and the shoulder 24 occurring at the junction of said head and the sleeve 20 and overhanging the head.

A portion of the core 19 at the upper end thereof is left exposed, 0., is not surrounded by the sleeve 20, and this exposed portion of the core is utilized to connect the valve 5 and the button 7 and projects into a central opening in the top of said button, vhich opening preferably has an hour-glass shape from end to end, as shown. The union of the valve and the button is completed by a filler of soft metal 25 which is poured in said opening in the top of the button, completely filling the same and of course taking a grip upon th corrugations of the bar 19. The opening in which the filling 25 is poured is closed at its lower end by a washer 26 which takes the thrust of the upper end of the spring 9 by which the valve 5 is held normally closed, the said spring being arranged in a recess 27 internal to the button 7 and at its lower end bearing against a washer or wear-piece 28 which is imposed upon the web 29 which intervenes between the recess 8 in which the button 7 works and the liquid passage 4 and snugly surrounds the sleeve 20. The wear-piece 28 preferably rests upon a packing ring 30, the oflice of which is to prevent any escape of gas from the passage 4- through the web 29.

Als previously stated, the siphon head proper is formed by compressing the material of which said head is composed in a suitable mold embodying properly shaped dies, and the said head requires no baking or other extraneous steps for its production, the use of a high pressure in the molding operation being all that is required. It is necessary, however, that the axial bore of the head which comprises the chamber 3 and the passage 4 should be of no greater diameter at its inner end than at its outer end, since it would be impractical to produce the head in the manner described were the bore of the head of greater diameter at its inner end than at its outer end.

The material of which the head is composed is thoroughly hygienic and sanitary, it is impervious to moisture and gases; it is capable itself of furnishing the required sealing surfaces by which the escape of gas at the various joints of the head and bottle neck and crevices or interstices is efliciently prevented; it is exceedingly tenacious, possessing great tensile strength and having no brittleness; it lends itself to desired ornamental configurations: it is relatively light in weight and of smooth texture; and may be quickly and inexpensively molded into the shape desired. Since the said material requires no baking to set it in its ultimate form, and is impervious to moisture and gas, the joint between the neck ring and the lower portion of the siphon head proper is greatly superior to the ordinary joint involving a soft metal neck ring.
